Xiubo Li 7a84a61347 ceph: do not access the kiocb after aio requests ... [ Upstream commit d1d9655052606fd9078e896668ec90191372d513 ] In aio case, if the completion comes very fast just before the ceph_read_iter() returns to fs/aio.c, the kiocb will be freed in the completion callback, then if ceph_read_iter() access again we will potentially hit the use-after-free bug.
